Justin Bieber has responded to his father’s reaction to his nude photos of the star taken by paparazzi that surfaced online.

The singer was photographed naked while on vacation in the South Pacific island of Bora Bora earlier this month (October).

Following the publication of the photos, Bieber’s father, Jeremy Bieber, took to Twitter to describe himself as proud, adding: “What do you feed that thing?”

Speaking on the Zach Sang & the Gang radio show, Bieber said of his dad’s response: “I thought it was hilarious. ‘What do you feed that thing’. It’s such a dad thing to say.”

Jeremy Bieber later deleted the tweet after criticism from fans online, which the singer says was unwarranted. “When I found out people were hating on him for saying that, I was like, ‘Are you kidding me?'” Bieber added. “What dad wouldn’t be proud of that? It’s not like he’s saying it to an 11-year-old. I’m 21 years old”
